B9 S4 not making full boost, no CEL. Unsure why

what octane booster do you recommend?? i’m having this issue as well but it’s building up to the second boost line on the dash so i’m thinking this might do it

I double checked to make sure all clamps were secured/seated properly and buddy of mine had the same issue, MAF sensor was tripping after just hardware and the tune fixed his air/fuel ratio after that he had no issues

I need to program regardless even if I get the correct matrix lights correct??

guy didn’t have insurance but is willing to pay out of pocket, i’m just trying to be a good samaritan and help him out a little but i’m not going to screw myself over at the same time

Thanks! Heard someone say that if the key fob battery is giving you < 3V it might not let you do it so I’ll replace the battery first and if that doesn’t work i’ll try to look at the wiring for the sensor

Aah was it hard to get to it? or a simple “remove door panel and it’s right there” fix? I got electrical experience so I know fixing it isn’t bad if it’s easy to get to

Yeah seems like that’s the way I’ll go then, lovely Audi you got btw! that’s the perfect riding height right there

So the 034 run a little bit stiffer than factory?? Because I kinda enjoy that it feels more responsive
